Specification of Iietters Patent.

Patented July 6, 1909.

Application filed June 19, 1908. Serial No. 439,369.

Be it known that-I, Russnu. II. CHALK, a eitizeii ol' the United States, and a resident oi Sonora, in the county of Sutton and State of Texas, have invented certain new and useful Improvements in Valves, of which the following, is a specification.

My invention'is an improvementin valvesv and consists in certain novel eonstructitms and combinations 01' parts hereinafter de scribed and claimed Referring to the drawings which form a parthereoi--Figu re 1 is a diagrannnntic view of the water supply-tank and the watering trough with the valve in position, Fig. .Lis a central longitudinal section of the valve, and

Fig. 3 is a section on the line Zi 3 of Fig". 2

The present embodiment of my invention comprises a valve easing Lsubstantmlly rec- .tangular in cross section, and having on one side an inlet 1 connected by a pipe 3 with the water supply tank 4, and onthe other with i an outlet 5 connected by a pipe 6 with the water trough 7, The inlet 2 is in alinement with the outlet 5, and o valve 8 is movable vertically in the casing, the said valve being rectangular in cross section to eorresptmd with the cross section of the easing. and beingprovided with an opening 9 theretln-ough, which when the valve is in its lowermost position is adapted to place the inlet '2 and the outlet 5-in communleation with each other.

The casing is provided with a eireular' flange 10, and a circular cover 11, is arranged on thetop ol' the casing, the said cover being secured to the ila-nge by means oi bolts 1;. The cover is provided at approxiunttely its center with [reopening encircled by onipple 13, the stem 14 of the valve passingtlu-ough the opening and the nipple, a packing 15 be.- ing arranged between the nipple and the stem. The nipple is externally threaded,

and. a peeking out 16 is engaged therewith,

the packing not having t portion 17 extend ing Into the nip plc for compressing the packing. i

A brqcket 18 is securedto one end of the casing by means of screws 19, and to the upper end of the bracket ispivotcd as at '20, it ever 21, having at its inner end a yoke 22, bet-ween the arms of which the stem is piv oted as at 23, and a cup .24 is provided with a bail 25, which is connected with the free end of the lever. The Water trough is pro vided with the usual float valve .26, andan overflow pipe 27 is arrangednear the upper edge of the trough, the overflow pipe hemp; provided with a depending portion 28 discharging, into the cup ".24 as shown in Fig. .1.

"The operation of the device is as follows: As long as the float valve o )Ll'lttOS properly, the 'ater will be shut oll' w ienever the float is in the position shown in Fig. 1. Should this device fail to operate for any reason, the trough will soon iill u )with water, which passing out through the overflow pipe 27 will enter the cup :24, and when the cup l'ull, the lever 21 will swing into the position shown in. Fig.5. L2,"thus cutting oil the inlet .2,

I'rom the outlet 5, and stoppin the llow ol' alined inlet and outlet openings, a valveslidahle in the casing, andhaving an opening normally registering with the inlet and out let, a, stein on the valve a bracket on the cits; ing, a lever pivoted omthe bracket, and hnv; his one endconnected with the stem, 2: cup connected with the other end of the lever,

' said eup beingarranged adjacent to the wateringtrough, the watering trough having an overllow pipe whose outlet; is arranged above the cup.

2. The combination with a water supply tank, and a watering trouglfconnected therewith, :tnil a lloat valve for controlling said connection, ofn valve casing interposed in the said conm-ction, a valve movable in the casing and normally out of position to close the connection, a pivotally mounted lever having one end connected with the valve, 4 cup on the other end, and an overflow pipe in connection with the watering trough to discharge into the cup.
